MEM23142 — Determine psychrometric processes and system performance

1 Review psychrometric processes

• 1.1Obtain and implement work health and safety (WHS) and environmental requirements for the work area
• 1.2Apply knowledge of psychrometric processes to analytical solutions to HVACR systems in accordance with organisational procedures
• 1.3Diagnose air temperature and humidity problems using psychrometric charts
• 1.4Consult appropriate personnel to ensure that work is coordinated effectively with others

2 Analyse the psychrometric and system performance of HVACR systems

• 2.1Determine plant or system capacity and airflow requirements for effects of coil bypass factor, apparatus dew point (ADP) and partial load control
• 2.2Calculate dehumidified air quantity using both target superheat (TSH) and effective room sensible heat (ERSH) methods
• 2.3Establish plant capacity and air flow rates for the system and/or building
• 2.4Establish airside systems and determine system performance
• 2.5Determine systemic performance parameters
• 2.6Consult on any contingencies and unexpected situations and take appropriate action based on specifications, codes and standards, and organisational procedures

3 Document and report on psychrometric and HVACR system performance

• 3.1Evaluate solutions to psychrometric and system performance to determine their effectiveness
• 3.2Report and document analysis in accordance with organisational procedures, incorporating details of all findings, calculations and assumptions
• 3.3Prepare and justify recommendations for any required actions in relation to HVACR equipment

What does an assessment tool for MEM23142 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM23142 needs to address all 44 unit components: 3 elements with 13 performance criteria, 9 performance evidence requirements, 22 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MEM23142?

Auditori pulls the current release of MEM23142 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MEM23142 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM23142 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MEM23142, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
